My mouth has generally been sore for several days. More specifically, the underside of my tongue is swollen and sensitive, my gums seem rough and are sensitive and not smooth, I had several swollen taste buds on the top of my tongue that did go away after a couple of days, and I have two sores in my mouth, one on the underside of my tongue and one on the piece that connects the bottom lip to the gums. I am 22 years old, female, I brush and floss regularly and do not frequently get canker sores. No recent food choices have struck me as being a contributing factor.
